Description:

In this webinar we will show the case study from the Paper that was presented by Marek HANACZOWSKI, M.Sc. bridge designer, in the Security of Bridges Congress that was celebrated in Wroclaw, November 25-26, 2021.

The paper presents the computational approach (FEM analysis) to accurately reproduce an impact on a bridge superstructure according to PN-EN 1991-1-7[3] and the several aspects that should be faced in a bridge design. Two different models of a precast concrete beam bridge were presented:

• Static linear analysis for the shell model with equivalent static impact force.
• Static nonlinear analysis including nonlinear concrete material model for the solid model

The simulations were performed with CivilFEM powered by Marc, a high-end general-purpose finite element software for civil, structural and geotechnical engineering, that combines concrete and steel structure Code Checking and Design with advanced nonlinear analyses.

The Nonlinear Concrete material model considers time depending material properties, cracking and post-cracking behavior: hardening, softening and residual stiffness, crushing, creep and shrinkage nonlinear steel reinforcement and bond-slippage between concrete and reinforcing steel and thermal-structural couple analysis for early age concrete (maturity), fire or ambient temperature variation.

Moreover, some other bridge typologies and impact models will be presented.
